Sources in Nokia’s Taiwan handset supply chain, quoted by DigiTimes, stated that the devices will target both ends of the lucrative worldwide smartphone market and be among the first to utilise the new OS version.

One of the devices that will be revealed is the Lumia 1820 that will have a Qualcomm Snapdragon 805 processor as well as a 5.2in qHD display and a powerful 3,400mAh battery.

Nokia also plans to release the Lumia 1520V, which will be similar to the Lumia 1520 but have a scaled down 4.45in screen and a 14-megapixel camera, with a 6in Lumia 1525 also expected to be unveiled at the conference, which runs from 24-27 February.

Nokia’s Lumia 1520 only arrived in UK stores on 6 December and is the firm’s largest, most powerful Windows Phone yet. The phablet-sized phone offers a 6in Full HD display and a 20-megapixel camera as well as a powerful Qualcomm Snapdragon 800 quad-core 2.2GHz processor.

These aren’t the first rumours surrounding Nokia’s preparations for MWC 2014 and an earlier report stated Nokia was looking to release Goldfinger and Moneypenny as the first Windows Phone Blue [8.1] devices.

Of those two, Goldfinger is the top end device and could have “3D touch”, which detects movement and interactions “off the glass” with the technology similar to that used in the Samsung Galaxy S4 smartphone. Moneypenny, meanwhile, is expected to be a dual-SIM Windows Phone.

There were also further reports that Nokia will release a Lumia 2020 8in tablet at the event.

Windows Phone 8.1, or Blue as it has been known for some months, will also see the light of day at MWC 2014 with a range of new features including a personal digital assistant known as Cortana, a new notification centre and improved multi-tasking.

Microsoft bought Nokia’s mobile devices unit and licensed its patents for 10 years in a deal worth £3.2 billion that was agreed late last year and it will be looking to arrest a decline that saw smartphone sales drop 29 per cent in Q4 2013.
